For gas absorption towers, is a packed tower more effective? Should we still use a plate tower?
Plate towers are superior; they offer good gas absorption performance and do not suffer from flow imbalance, thus ensuring effective absorption. In my opinion, all the large-scale gas absorption towers I have seen are of the plate type – this is just for reference
In terms of pressure drop and efficiency, packing is preferable; if the gas is quite \"dirty,\" then one should consider using a random bed or opt for a plate tower.
Small towers use more packing; simply insert the packing inside the shell, and their efficiency is also much higher than that of plate-type towers. Large towers that operate on a continuous basis in the chemical industry use plate-type designs
It mainly depends on the medium; some that contain dust or similar substances are not suitable for use with packed towers.
